Key Benefits and Advantages
-
High Capacity for Commercial Loads: With the ability to support over 2.6 million BTU/hr, the HSRL can easily manage the combined load of multiple high-demand appliances, such as commercial boilers, large-scale water heaters, and industrial furnaces.
-
20-Year Recommended Replacement Life: The HSRL is built for longevity. Using high-grade materials and corrosion-resistant finishes, this regulator offers a two-decade service life, providing a low total cost of ownership for gas distributors and property managers.
-
Improved Regulation Accuracy: Precision engineering of the internal spring and diaphragm ensures that the outlet pressure remains stable even during significant fluctuations in gas demand. This prevents appliance pilot outages and ensures peak equipment efficiency.
-
Advanced Overpressure Protection: The HSRL Series includes an integrated internal relief valve. This safety feature ensures that in the event of an internal failure, excess gas is vented safely, keeping the downstream pressure within levels that protect the building’s internal plumbing and appliances.
-
Positive Drainage and Venting: The regulator features a screened drip-lip vent oriented over the inlet as standard. This configuration allows condensation and moisture to drain away from the internal spring case, preventing icing and corrosion in cold or humid climates.
-
Corrosion-Resistant Construction: To withstand the rigors of outdoor placement, the HSRL utilizes robust alloys and specialized coatings that resist atmospheric degradation and chemical exposure.
-
UL Listed: Full compliance with Underwriters Laboratories standards ensures the regulator meets the highest safety and performance criteria for the propane industry.

Field of Application
The HSRL Series is designed for “heavy-lift” gas regulation where domestic-sized regulators would fall short of the required flow volume.
Primary Industries and Uses:
-
Large Commercial Buildings: Providing gas service for multi-unit apartments, hospitals, and office complexes.
-
Industrial Kitchens: Supplying a steady, high-volume gas flow to commercial ranges, fryers, and ovens.
-
Agricultural Applications: Regulating propane for grain dryers, greenhouse heaters, and livestock buildings.
-
Light Industrial Process: Reliable pressure control for small manufacturing plants and warehouses using gas-fired heating.
